HORACE N. TUCKER, OF STOUGHTON, MASSAOHUSETTS.-

IMPROVEMENT IN WASHING-MACHlNS.

Specification forming part of Letters Patent No. 186,902, dated January30, 1877; application led April 10. 1876.

To all whom it may concern:

Be it known that I, HORACE N. TUCKER,

of the town of Stoughton, in the county of Norfolk and State ofMassachusetts, have invented certain new andfuseful Improvements inWashing-Machines; and I do here by declare that the following is a full,clear, and exact description of the character, construction, and'operation of the same, reference being had to the accompanyingdrawings, which make part of this specification, in

which the ligure is a front elevation, partly 1n section, ofthe machine,showing the two rollers, posts, bed-piece, top rail, &Jc.

My improvement relates to a new and imf crank alternately in oppositedirections until the clothes are quickly and thoroughly cleansed, thejournals of the upper roller working in slots, and held down by themetallic bearings and springs, which yield for the passage of buttons orother variations in thickness. 4

The advantages of my improvement in the upper roller consist in that theclothes are fed through more surely, and are less liable to becomeentangled on the rollers; and it also acts with greater efficiency inremoving the dirt from the clothes by being thus doubly corrugated.

I make the frame of the working apparatus of the bed-piece A, into whichare fitted the posts B U, which, after receiving the roller D, aresecured by screws or otherwise. I furnish the posts B and C withmetallic journal-bearings h and z', for the journals of the roller E toWork in, and also to hold in place the journal-bearings a b. Afterplacing the upper roller E, I put into the slots of posts thejournal-bearings a b, around which are placed the springs c d. I thenfit the top rail Gr with holes, in which the upper ends of the bearingsa and b play, and secure it to the posts by screws or otherwise.

I make the roller D with transverse beads and grooves, and the roller Ewith both transverse and longitudinal beads and grooves, and so arrangedthat the most depressed portions of the one roller will receive theprominent portions of the other, so that when the upper roller E isrevolved the friction of the grooves and beads will cause the roller Dto revolve in the opposite direction, so as to feed the parcel to beWashed through in either direction.

I ft the bed-piece A to any common washtub, in which holes are bored to-receive the dowels e and the slide-bolt g, which dowels and bolt,together with the friction of the tub and ends of the bed-piece A, holdthe machine in position.

To use this machine I put into the tub a suiiicient quantity of hotWater, and put in the clothes, they having been previously soaped andfolded to correspond with the length ofthe machine. l then put one endof the parcel (which may consist of several pieces folded together)between the rollers D and E, and revolve the crank H until the parcelhas passed nearly through, then turn in the opposite direction, and soon until the articles are fully cleansed.

Having thus described my invention and its advantages, what I claim asnew, and des;re to secure by Letters Patent, is-

1. The combination of a roller, E, provided with alternatingcircumferential depressions and elevations, and with longitudinalcorrugations formed in said elevations, with one or morecircumferentially-corrugated rollers, D, as constructed and arrangedwith relation to each other, for the purposes set forth.

2. The roller E, having transverse elevations and depressions of equalwidth, height, and depth, and provided with longitudinal slots in theelevations, as shown, in combination with one or more rolls, D, havingcorresponding elevations and depressions, and so arranged relatively tothe upper roll as to mesh therewith throughout its whole extent, as andfor the purpose specified.
